Fulton Bolt On Folding Trailer Tongue Swing Away Hinge Kits are ideal for boat trailers that can be just a little too long to fit inside smaller garages, shops, and other restrictive spaces. Designed to convert standard trailer tongues into fold-away configurations, the Fulton fold away hinge kit 2x3 delivers strength at the pivot point with precisely machined heavy-duty hinges made from die cast steel. An attractive yet durable zinc coating helps prevent rust and corrosion on the trailer tongue hinge kit. The easy to install bolt-on application comes with a complete instruction manual for hassle-free installation and includes all mounting hardware for the swing hitch. The Fulton Fold-Away Bolt-On Trailer Tongue Hinge Kit fits trailer tongues with outside dimensions of 2 inches x 3 inches with a material thickness between .188 inches and .120 inches. For use with steel tongues only.
